Abstract
We give a sufficient condition for essential self-adjointness of symmetric operators associated with classical Dirichlet forms on Hilbert spaces. The condition implies a one-sided restriction on the derivatives for a suitable approximation of the drift coefficient β but does not involve L p or smoothness conditions on β.
